I'm not sure if there is anything I can do about it. Scrolling is all handled by the Android Open Source Program. You might consider submitting a bug there.

For those who might be interested as to the root cause of this issue, the webpage in the example video has a section (the issue chart) that can scroll left and right. When swiping up and down to initiate a fling (rapid scroll), Android will often interpret it as a normal scroll instead of a fling if your finger travels even a little left or right (because it thinks you might be trying to scroll the underlying content horizontally). My experience is that newer versions of Android have better logic at deciding what to do with the scroll input, but there is probably still some room for improvement in the algorithm.
